i'm trying to create a publication and its snapshot in the default snapshot folder of MS SQL Server 2005.
It's all done by RMO.
Following Scenario:
1. PublicationDB was created by User1(sysadmin) ... successful
2. Enable PublicationDB for Publishing ... successful
2. Creating the publication: executed as User2(db_owner)
2.1 publication.Create(); ... successful
2.2 publication.CreateSnapshotAgent(); ... successful
2.3 Add Articles to publication ... successful
2.4 Generate Snapshot with
agent = new SnapshotGenerationAgent(); and setting all parameters for it, then execute by
agent.GenerateSnapshot();
And at this point,i got an error message, because the snapshot agent cant be executed ...2007-09-12 12:05:46.58 User-specified agent parameter values:

Configurations:
-All Users have rights for read and write on the snapshotfolder including the Agent
-All users are defined in the same windows domain
-the snapshotagent account has sysadmin rights on the server and is assigned to the predefined MS SQL User Role
This scenario is workin completely fine when i exceute everything as a "sysadmin"!
But when executing it all as "db_owner" of the database, its not workin!!!
Does anybody has any resolutions for this problem?
I appreciate any support.

Hi,
Just double check, when you say the account is 'db_owner', is it an db_owner of both publication database and distribution database? Replication requires both. For complete replication agent security requirement, you can refer to http://technet.microsoft.com/en-us/library/ms151868.aspx
If it still does not work, please let me know.

|||Hi,thx for your reply.
I read already a lot about it in the msdn, also that link that you mentioned. I found out about the proxies and credentials used by sql server.
Following:
When creating the publication by a User (db_owner), it only works when the User has db_owner rights for both, the publication and distribution database. But i dont want to grant this user account the db_owner rights for the system database 'distributionDb'. Thats i would like to solve it by impersonating and that process account for the agent.
I also created the windows account "repl_snapshot" just for the Snapshot Agent.
When creating the Snapshot agent for the publication, i also use the "impersonating ... process account", therefore the "repl_snapshot" should excecute the snapshot creation, cause the agent is defined like this. When creating this snapshot agent: the proxy and credential are automatically created.
Next point is that i need to assign the account User1 (db_owner) to that proxy, right?!
But then i get the message:
it starts the agent ... success
executing ... no rights!
and then! Big problem ... nothing works anymore on that database. and then i need to use the sp_removedbreplication and create a new db.
So i dont understand completely how to configure this proxy for this agent job. Cause i found out, that i need to assign the proxy to each agent job step, but i cant do that! cause when i open the agent job to assign the proxy to the steps: no steps are shown. But when starting the agent job over the context menu, i shows the three steps, sth like: start egent, execute, end.
What do you think? Am i on the right way?
I think, I will have the same problems when creating/Synchronizing a subscription form an sql express server for the merge Replication at the end, cause there is also the 'repl_merge' merge agent as the process account.

Hi,
When you create the publication and configure snapshot agent, there are two sections in the "snapshot agent security" dialog: a windows account that snapshot agent process that runs under (snapshot agent use this account to connect to distributor), and if you would like to connect to publisher by impersonating process account. You need to assign the db_owner role to the proxy account to the distribution db and publication db (if you choose to connect to publisher by impersonating process account). From your reply, it is still not clear to me if you assign the db_owner role to the proxy account at both distribution/publication DB.
To use another proxy account or simply sqlagent service account for snapshot agent, goto "publication properties" dialog and choose "agent securities" tab and you should be able to launch "snapshot agent security" dialog and modify it.

hi,
Sorry if it wasnt clear. Indeed, i did assign the db_owner role to the proxy account at both distribution/publication DB.
Its just that i want to run that Snapshot agent in a context of a proxy and thats not working, so i found out sth on the Support page of Microsoft. Microsoft has a hotfix for exactly that problem, i think ... i didnt try it yet ... but for sure im going to do that on monday.
Hotfix: A SQL Server Agent job fails when you run the SQL Server Agent job in the context of a proxy account in SQL Server 2005, http://support.microsoft.com/kb/938086
Will let you know for more when i've tested it ...

|||Its working with this hotifx!!!!So, wait for SP3 or get this hotfix update if you really need it, but the hotfix is not fully tested and official.
